The coal mines safety standards are reviewed every year by the Standing Committee on Safety in Coal Mines under the Chairmanship of Minister of Coal. These safety standard were last reviewed on 23.12.2010 wherein the following suggestions were given to improve the coal mines safety standards:-
Ø Design of system of support of roof in the development workings in underground mines by scientific support systems based on Rock Mass Rating (RMR) studies.
Ø Increased use of Roof Bolting / Roof Stitching methods of support using steel roof bolts/ steel wire ropes with quick setting cement grout to arrest bed separation at early stages to impede deterioration of roof.
Ø Introduction of modern drills like mechanised drilling machine to avoid exposure of support personnel to unsupported roof while drilling for roof bolting and greater use of quick-setting cement/resin capsules grouted roof bolts for support in development workings in underground mines.
Ø Reduced exposure of workers to mining hazards by mechanization of loading operations by increasing use of Side Discharge Loaders (SDLs) and Load Haul Dumpers (LHDs) in belowground mines, Powered Support Long Wall (PSLW) system of mining, Continuous Miner Technology etc., are being progressively adopted in suitable areas.
Ø Regular monitoring of mine environment by handheld gas detectors/alarms and flame safety lamps for detecting inflammable and noxious gases. Besides, for early detection of situations that could lead to an outbreak of fire or an explosion, highly capital intensive computerized continuous mine Environmental Tele Monitoring System (ETMS) have been installed and are in operation in thirteen identified underground mines.
Ø Introduction of surface miner, an eco-friendly technology to reduce hazardous operation like drilling, blasting and crushing wherever applicable.
